Lesson7: ERROR TransactionExecutionError: Transaction ran out of gas

[udayg24]

I am stuck at local testing. when i try to test the withdraw function it shows following error.

withdraw
         withdraw eth from a single funder:
     TransactionExecutionError: Transaction ran out of gas 

describe("withdraw", async function() {
        beforeEach(async function() {
            await fundMe.fund({ value: sendValue })
        })

        it("withdraw eth from a single funder", async () => {
            // Arrange
            const startingFundMeBalance = await fundMe.provider.getBalance(
                fundMe.address
            )
            const startingDeployerBalance = await fundMe.provider.getBalance(
                deployer
            )

            // Act
            const transactionResponse = await fundMe.withdraw()
            const transactionReceipt = await transactionResponse.wait()
            const { gasUsed, effectiveGasPrice } = transactionReceipt
            const gasCost = gasUsed.mul(effectiveGasPrice)

            const endingFundMeBalance = await fundMe.provider.getBalance(
                fundMe.address
            )
            const endingDeployerBalance = await fundMe.provider.getBalance(
                deployer
            
)

            // Assert
            // Maybe clean up to understand the testing
            assert.equal(endingFundMeBalance, 0)
            assert.equal(
                startingFundMeBalance.add(startingDeployerBalance).toString(),
                endingDeployerBalance.add(gasCost).toString()
            )
        })
    })

i even copied patrick's code, but it doesn't work.

here is the github repo link of the project:

@udayg24 Try to add gas manually like this:

rinkeby: {
  url: process.env.RPC_URL,
  accounts: [process.env.PRIVATE_KEY],
  chainId: 4,
  blockConfirmations: 6,
  gas: 6000000,
},

@udayg24 Onc dependency that you did not have and it is required so we can use ethers from hardhat-deploy

npm i --save-dev @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers@^0.3.0-beta.13

@udayg24 Now it is working, going to push it to your repo, check it.

[udayg24]

its working!
can you tell me what was the problem with the code?

[alymurtazamemon]

@udayg24 mentioned above!

[udayg24]

got it, thanks!

Hey @udayg24 are you running this on a testnet or locally on hardhat network?

[udayg24]
